Weather is the day-to-day natural environmental processes that occur within the lower atmosphere of a planet. Weather was defined by the present or future conditions such as hot/cold, humid/dry, fair/cloudy, or calm/stormy in any one area. Patterns or trends in weather conditions were used to determine a region's climate.
Study of weather 
Edit
Meteorologists were those who meteorology, which was the science of weather conditions. One whose occupation involved reporting the weather was known as a weatherman or weather coordinator.
On Earth, during the 20th century, weather was studied by means of weather balloons or weather satellites.
By the 24th century, technologies such as a weather control system or a Weather Modification Net could be used to control the weather on a planet, as was the case on Caldos, Hekaras II, Risa, and Earth during the late-24th century. (TNG: "True Q", "Sub Rosa", "Force of Nature")
Without this technology, some planets had harsh climates. For example, after Risa's weather modification network was shut down in 2373, several lightning storms quickly formed with thunder and rain. (DS9: "Let He Who Is Without Sin...")
